Add profession counterparts to the burner & hazmat zombie(+change napalm's "container" & a new itemgroup)

[ghost]

Summary

SUMMARY: Content "Add profession versions of the burner and hazmat, restore mask cartridges on 2 profs"

Purpose of change

Both zombie burners and hazmat zombies exist, but there is no profession version of them to play as. As every other professioned zombie(soldier/cop/bio-operator/SWAT) has a roughly equivalent profession counterpart, these also should.

Also, two professions spawn with empty gas masks.

Describe the solution

Add a corpse disposal and a hazmat unit profession, using mostly the same gear as the zombie version. Changed napalm's container to a pressurized tank to accomplish this.

Use new itemgroup to add mask cartridges to the Military Corpse Disposal, Riot Control Officer, and Miner.

Describe alternatives you've considered

Giving the corpse disposal unit an ESAPI vest and/or giving it a back holster & autowielding a jerrycan of napalm(which would make it wildly OP as that's 100 shots of a type near-every mob has no resistance to).

Testing

Look at both ingame.

Additional context

The corpse disposal unit would be the only mainline profession with inherent launcher skill, neat!

Napalm doesn't spawn in mainline or first-party mods except inside monsters like AFS's tripod or a drop inside of a burner's flamethrower, so changing its container should do nothing to its prevalence. Its container had to be changed to a pressurized tank to both make it spawnable inside the flamethrower & keep them debug-spawnable.
